among Common Ravens
观察细节
a bit of a stretch to include this bird. I got a text from N.S. at 10:48 about a Bald Eagle flying northwest over Huntington. I started observing the skies (with image-stabilized 10x42 binoculars) from my location near the northern settling ponds and saw the (presumed) eagle flying westbound about 1.5 miles to the south at 10:59, eventually going below the hill to the south of the basin. It was not really identifiable to species at this distance, but the circumstances support this i.d. It was clearly a large raptor, with broad rectangular wings characteristic of eagles, with about twice the wingspan of the CORAs harassing it. (There was a large kettle of those in this general direction, but the eagle did not join the kettle.) It circled a few times, making occasional wing beats consistent with a very large bird. It otherwise flew with wings held flat (not dihedral), and it was not observed to teeter like a TUVU. All birds were silhouetted at this distance, near the horizon, and it was even difficult to pick up the white from the AWPE flying in the area about the same time. There were two RTHA mixed with ravens at about the same distance, and the flight style and size comparison with CORA were clearly distinguishable from the eagle.
